Management's own plan, taken literally. Corning states an annualised run rate of $20 billion by the end of 2026, $30 billion by the end of 2028 and $40 billion by the end of 2030, and a 19% sales CAGR from Q4 2026 to Q4 2030. On the run-rate definition Corning's own filings prove - Q4 core sales times four, since Springboard 'launched with an annualized sales run rate of $13 billion' against Q4 2023 core sales of $3,272m - that resolves to Q4 2030 core sales of $10,000m. The base case gets to $9,129m, so this case adds 0.75 points a quarter to Optical Communications alone, which is where the brief's arithmetic puts the burden: the other four segments cannot carry it. It reaches a $40.0 billion run rate. What it does NOT do is change the exit multiple or the discount rate - it is worth $165.54 a share, so even delivering the plan in full leaves the stock roughly 8% undervalued rather than transformed, because at 28x today's EBITDA a great deal of the plan is already in the price.

Ceramic substrates and particulate filters for emissions control, plus Automotive Glass Solutions. A mature, cyclical, cash-generative line with a 30.36% EBITDA margin and essentially no growth at +2.4% year over year. Its job in the model is ballast: it funds the build without being asked to grow into it.

Assumptions & reasoning

  • Two years of segment EBITDA margin sit in a 28.7-30.7% band with no trend, so the terminal margin is held mid-band rather than extended in either direction.
  • Terminal capex intensity is set to the FY2025 rate of 4.24% rounded to 4.0%, not to the 3.40% of one light quarter, because 16 of capital spending on 471 of sales is a quarter of maintenance-only spend rather than a run rate.
  • The segment was created on 1 January 2025 by moving Automotive Glass Solutions in with Environmental Technologies and Corning did not recast 2023, so only ten quarters exist on this definition - which is also what sets the model's shared history window.
